Forces And Motion

Question 1

The force on multiple objects stays equal no matter

Answer 1

how much extra mass is added to one of them - any two objects will have the same gravitational force towards each other

Question 2

Inertia is

Answer 2

the tendency of mass to maintain its state of motion

Question 3

Cause

Answer 3

(The force)

Question 4

Effect

Answer 4

(The acceleration)

Question 5

The force that attracts the moon to the earth is….

Answer 5

exactly the same size as the force that attracts the earth to the moon

Question 6

As the earth has a greater mass it has a greater inertia

Answer 6

so even with the same amount of force on it, it doesn’t accelerate that much
